The earthquake and the aftermath
• GNS says today's earthquake released 30 times as much energy as the devastating Christchurch earthquake but was dispersed across a far greater area. • The initial 6.6 magnitude earthquake, revised to 7.5, was 15km deep and struck at 12.02am not far from Hanmer Springs in North Canterbury in the South Island. • GeoNet says the 7.5 quake is from two separate earthquakes, which is why there are aftershocks in two locations. • More than 380 aftershocks have rocked the country with 216 tremors making it over magnitude 4. • At least two people have died amid reports of many other casualties. One victim suffered a heart attack, another was killed in a historic homestead in Kaikoura. • It is understood a number of people in the North Canterbury region were treated after suffering non-fatal heart attacks after the quake. Several have occurred at evacuation centres. • Tsunami warnings have been lifted. • Prime Minister John Key has called off his trip to Argentina to manage the fallout from today's deadly quake. • Update: 245 emergency calls have been taken by @NZFireService since the 12.02am quake (nationwide). • MetService has issued a weather watch for heavy rain and severe winds for parts of the country including Marlborough and North Canterbury. Gusts of 140km/h are likely in exposed places.

Communication • Vodafone is conducting a full assessment of mobile and fixed-line networks. A fewsites are down. • Damage to physical infrastructure and power outages in Kaikoura are causing connectivity issues for Spark mobile, landline and broadband customers • Five cell sites in Kaikoura are still down, so nearby homes may not have access to the Spark mobile network until tomorrow • Six other cell sites in Canterbury are being powered by backup batteries - Spark will ensure these sites will be reconnected to the mains or a backup generator • All but one cell site have been restored in Wellington, but Spark said customers near the offline site should be in range to connect to other sites • A few hundred homes in North Canterbury have broadband again, now that power has come back on for many areas • But 1700 households still can't use their Spark broadband or landline services • The fibre cable connecting Kaikoura to the national broadband network, which runs along SH1, has been badly damaged. The cable has been severed in the north and south of the town and it may be weeks before broadband is reconnected • Spark technicians have flown into Kaikoura and looked at the local telephone exchange • Kaikoura's local phone service is working, so residents can call others in the town, but can't call outside areas • The entire South Island is depending on Spark's western landline and broadband cable which runs from Blenheim to Christchurch via Greymouth for connectivity to its service because the east coast cable is broken • If the western cable breaks the entire island may go offline • Spark's customer service staff are available via online chat, the Spark app and website • Spark's Willis St and Queensgate stores in Wellington, Moorhouse Ave store in Christchurch and Blenheim store will be closed tomorrow

Possible scenarios • Likelihood 80% and greater A normal aftershock sequence that is spread over the next few months. Felt aftershocks greater than magnitude 5 would occur from the epicentre near Culverden in the next few weeks and months. This is the most likely scenario. • Likelihood 60% and greater The rupture of earthquakes at magnitude 6 in the North Canterbury and Marlborough regions will occur, as well as potentially offshore in Southern Cook Strait and offshore Kaikoura. • Likelihood less than 40% The least likely scenario is that in the next month longer known faults would rupture with magnitude 7 quakes in the Marlborough and Cook Strait regions. Aftershocks could occur anywhere in the upper South Island.
